Is there any way i can change keyboard scroll (arrows) to WASD?
Unfortunately it’s not possible natively. Some people used a third party program called AHK that rebinds keys at the operating system level (Meaning it applies to everything, not just Warcraft 3, and it requires either a complete restart or closing the program, not sure which) so they can press WASD and the system thinks they pressed the arrow keys instead.
Unfortunately if you’re on MAC, that method also does not work.
